Product Introduction

The 800 kVA epoxy resin cast class F dry type transformer was delivered to South Africa in 2022.

 

The rated power of the transformer is 800 kVA with AN/AF cooling, the primary voltage is 6.6 kV with ±2*2.5% tapping range (NLTC), the secondary voltage is 0.55kV with delta star connection.

 

Cast resin technology provides excellent insulation and environmental protection, this together with the foil winding technology inside the resin offers the ultimate dry type transformer in terms of dielectric performance and short circuit withstand ability and ensures long term reliability for both distribution and special applications. cast resin transformers can be supplied with either aluminum or copper windings together with possibility of class F or class H insulation system, they can be designed to in-door or out-door installation with different enclosures.

 

We ensure that each one of our delivered units has undergone rigorous full acceptance testing. We provide one-package service from consulting, quoting, manufacturing, installation, commissioning, training to after sale services, our products are now operating in more than 50 counties in the world. We aim to be your most reliable supplier as well as your best partner in business!
